I'm thinking of getting a new faster/fitness bike and I've narrowed it down to two brands but four models in total. '08 Trek 7.5 - 7.6 FX and '08 Cannondale RW 2.0 and 3.0. I am currently riding a '04 Marin Larkspur (small frame 15.5) and I'm thinking of getting 17.5, I'm 5'8" btw. I have tried the Jamis Coda Elite but it does not feel right for me and it does not shift or go through the gears smoothly, but it is a fast bike don't get me wrong. It's a very nice bike! I'll try the FX tomorrow and the Cannondale on Sunday depends on my work load though. But need your expert advice. TIA
